I want to travel to Harbin alone in winter vacation, and I want to go by train. Fly back. About 10 days. What is the budget?

My home is Mianyang, Sichuan, and I study in Harbin. You can refer to it Air tickets are generally around 1500, and sometimes there are cheaper air tickets depending on your luck. The train ticket has 500 sleepers and 300 hard seats. Harbin Seven Days Hotel seems to be 170 a night. Eat, eat snacks while walking, etc. It's a day in 50 yuan. If you want to eat authentic Russian western food, it will definitely be more expensive. There are more than 300 tickets for the World of Ice and Snow and the Polar Pavilion. If you join a tour group to go to the snow again, it may cost about 1000 to go skiing in Yabuli, as well as the cost of taking a bus, taking a taxi and buying souvenirs. You can do the math.
